MATHEMATICAL MODEL OF PSYCHO-PHYSIOLOGICAL ADAPTATION OF INTERNATIONAL STUDENTS THROUGH DOSED PHYSICAL ACTIVITIES

Adaptation to a foreign culture environment represents one of the major problems that international students encounter upon arrival in another country. From the very first days at a university, international students stay in an unfamiliar sociocultural, linguistic and ethnic environment, to which they must adapt within the shortest possible time. The adaptation process itself, in this case, is quite complicated and includes several types of adaptation: physiological, individual psychological, socio-psychological, ethno-psychological, cultural, communicative, etc. All these types of adaptation, especially at the initial stage of studying, manifest themselves simultaneously and represent serious obstacles in both cognitive and communicative activities. Therefore, the identification of factors contributing to an increase in efficiency and acceleration of the course of adaptation processes among international students is an integral part of solving the problem of adaptation of this contingent of students. We consider psychophysiological adaptation as the most essential component of the entire adaptation process. In this paper, we propose a mathematical model, which represents a boundary value problem for an ordinary differential equation. Graphs explaining the main provisions of the model are presented. Cases of adaptation processes in the presence of cyclic processes are considered. The optimal physical activity promoting the most rapid adaptation is determined.
